1. A drive device for a deployable vehicle flap, comprising:
a flap part associated with the vehicle flap,
a body part associated with a vehicle body,
a first joint arrangement being arranged between the flap part and the body part, comprising a first knee lever and a second knee lever, wherein the first knee lever and the second knee lever each comprise a first control arm and a second control arm, wherein the first control arm of the first knee lever and the second control arm of the first knee lever are hingedly coupled to one another and are rotatable relative to each other about a first knee joint rotation axis, wherein the first control arm of the second knee lever and the second control arm of the second knee lever are hingedly coupled to one another and are rotatable relative to each other about a second knee joint rotation axis,
a second joint arrangement for opening and closing the vehicle flap in a normal operation,
at least a first actuator for raising the vehicle flap to a pedestrian protection position,
wherein the first actuator has a first connection element and a second connection element,
wherein the first connection element of the first actuator is hingedly coupled to the first knee lever of the first joint arrangement,
wherein the second connection element of the first actuator is hingedly coupled to the second knee lever of the first joint arrangement,
wherein the first connection element of the first actuator is hingedly coupled to the second control arm of the first knee lever at a distance from the first knee joint rotation axis, and
wherein the second connection element of the first actuator is hingedly coupled to the first control arm of the second knee lever at a distance from the second knee joint rotation axis.
